Consequences of Minimal Length Discretization on Line Element, Metric Tensor and Geodesic Equation
Abdel Nasser Tawfik, Abdel Magied Diab, Sameh Shenawy +1
When minimal length uncertainty emerging from generalized uncertainty principle (GUP) is thoughtfully implemented, it is of great interest to consider its impacts on {\it "gravitat…
Concircular curvature on warped product manifolds and applications
Uday Chand De, Sameh Shenawy, Bulent Unal
This study aims mainly at investigating the effects of concircular flatness and concircular symmetry of a warped product manifold on its fibre and base manifolds. Concircularly fla…
The -curvature tensor on relativistic space-times
H. M. Abu-donia, Sameh Shenawy, A. A. Syied
This paper aims to study the -curvature tensor on relativistic space-times. The energy-momentum tensor T of a space-time is semi-symmetric given that the -curvature tensor is…
Gray s decomposition on doubly warped product manifolds and applications
Hoda K. El-Sayed, Carlo Alberto Mantica, Sameh Shenawy +1
A. Gray presented an interesting invariant decomposition of the covariant derivative of the Ricci tensor. Manifolds whose Ricci tensor satisfies the defining pr…
On generalized quasi-Einstein GRW space-times
Uday Chand De, Sameh Shenawy
Recently, it is proven that generalized Robertson-Walker space-times in all orthogonal subspaces of Gray's decomposition but one(unrestricted) are perfect fluid space-times. GRW sp…
On the boundary of closed convex sets in
M. Beltagy, S. Shenawy
In this article a class of closed convex sets in the Euclidean -space which are the convex hull of their profiles is described. Thus a generalization of Krein-Milman theorem\cit…
